I believe you are thinking of the Normans (a historic group of people from Northern France), not the Mormons (a religious group begun in 1830). The Normans were participants in the Reconquista in Iberia, which took place from about 711 to 1492. During the Reconquista, European Christians fought the Muslim Kingdoms on the Iberian Penninsula. The new ideas that the Normans and other Reconquista participants would have brought to the area were religious beliefs and political models, as well as technology - specifically military technology.

The Patriot Act does not target any individual religious group. If a certain religious group feels as if they are being targeted by the bill, it is most likely because they fit a specific profile. You may, in theory, be more inclined to be targeted if you are of Middle Eastern decent due to the common threat coming from that region. However, it would not be based on you religious involvement. Ideally the bill is nondiscriminatory and will not target any race, color, sex, religion, etc., but the people enforcing the law may be prejudice and create feelings of unease.
